Same image as the previous movie (14) but with colour Doppler. This shows normal laminar (blue) systolic downward flow out through the pulmonary artery. There is a very tiny (red) diastolic flame of valvular regurgitation which is acceptably normal (see still below).

This is a good position to obtain a spectral Doppler velocity tracing of the speed of flow out through the pulmonary artery (see images below).

Still image below: Systolic frame showing normal laminar (blue) systolic downward flow out through the pulmonary artery.

Still image below: Diastolic frame showing a very tiny (red) diastolic flame of valvular regurgitation which is acceptably normal.

Still image below: Systolic frame showing normal laminar (blue) systolic downward flow out through the pulmonary artery. Peak velocity is ~1.0m/s.
